announcement
No. 54 of.2009
In order to implement the "Environmental Protection Law of the People's Republic of China", protect the environment, and protect human health, we now approve the measurement of total organic carbon in water quality.
Six standards, such as the combustion oxidation-non-dispersive infrared absorption method, are national environmental protection standards and are released.
The standard name and number are as follows.
I. Determination of total organic carbon in water by combustion oxidation-non-dispersive infrared absorption method (HJ 501-2009);
2. Determination of brominated volume of volatile phenols in water (HJ 502-2009);
3. Determination of volatile phenols in water - 4-aminoantipyrine spectrophotometric method (HJ 503-2009);
4. Determination of ozone in ambient air - Spectrophotometric method of sodium indigo disulphonate (HJ 504-2009);
6. "Electrochemical Probe Method for Determination of Dissolved Oxygen in Water" (HJ 506-2009).
The above standards have been implemented since December 1,.2009 and published by the China Environmental Science Press. The standard content can be found on the website of the Ministry of Environmental Protection.
The following seven national rings approved and issued by the former National Environmental Protection Agency or the former State Environmental Protection Administration from the date of implementation of the above standards
The environmental protection standards are abolished. The standard names and numbers are as follows.
1. "Measurement of total organic carbon (TOC) for water quality by non-dispersive infrared absorption method" (GB 13193-91);
2. Determination of total organic carbon in water by combustion oxidation-non-dispersive infrared absorption method (HJ/T 71-2001);
3. Determination of volatile phenols in water quality and bromination capacity after distillation (GB 7491-87);
4. Determination of volatile phenols in water - 4-aminoantipyrine spectrophotometric method after distillation (GB 7490-87);
V. Determination of ozone in ambient air - Spectrophotometric method of sodium indigo disulphonate (GB/T 15437-1995);
6. "Determination of the Biochemical Oxygen Demand (BOD5) on the 5th Day of Water Quality Dilution and Inoculation Method" (GB 7488-87);
VII. Determination of Dissolved Oxygen in Water by Electrochemical Probe Method (GB 11913-89).

Foreword
To protect the environment and protect the human body in order to implement the Environmental Protection Law of the People's Republic of China and the Law of the People's Republic of China on Water Pollution Prevention and Control
This standard is established for the determination of the five-day biochemical oxygen demand (BOD5) in the water.
This standard specifies the method for determining the dilution and inoculation of BOD5 on surface water, industrial wastewater and domestic sewage.
This standard is a revision of the "Dilution and Inoculation Method for the Determination of Biochemical Oxygen Demand (BOD5) on the 5th Day of Water Quality" (GB 7488-87).
This standard is modified to use ISO 5815-1.2003 "Determination of water quality n day biochemical oxygen dem
